BG Products were formed way back in 1972 in Wichita, Kansas, USA and have a significant catalogue of
collaborations with OEM's in finding solutions to specific deposit and sludging issues. The Company
believes that all cars suffer from carbon deposit issues – because burning fuel releases carbon –
always!

Decarbonisation or engine carbon cleaning usually refers to the process of removing carbon
deposits. BG Products develop and manufacture their own high quality chemistry and delivery systems
to do this, safely and effectively. Other proprietary systems use different classes of chemistry,
hydrogen, hot water or warm oil.

BG prefer not to comment on the effectiveness of other cleaning methods and services. BG Products
do, however, regularly demonstrate and publish their results, for instance, showing that BG fuel
system cleaners contain more of the chemistry recommended by the engine manufacturers themselves to
remove the hard baked carbon deposits that interfere with efficient flow of air and fuel,
throughout the entire system.

Normal servicing does not clean the inside of an engine and that is why many garages like industry expert Frank Massey recommend using BG 44K/BG245 and BG EPR as standard to clean inside an engine every service.

Deposits are a natural ongoing by-product of combustion and without preventative maintenance they will accumulate over time.

BG recommend a dedicated, dual approach – one product for the top half of the engine, to tackle fuel system issues and one for the bottom half, the oil system.

Fuel System: Deposits attach themselves to valves, piston crowns and fuel injectors. When fuel injectors get deposits on their fine spray holes (which they inevitably do) it can interfere with the ability of the injector to atomise the fuel into the engine. A fuel system cleaner will help to stop this happening and keep your engine running optimally.

Oil System: Cylinder compression is vital for a vehicle's Power and Economy. As a vehicle's piston moves it squeezes a fuel/air mixture in the cylinder, giving it explosive power. Rings around each piston ensure a good seal. Loss of compression (and therefore power) is usually due to deposits restricting these rings. A BG Engine Performance Restoration flush will clean deposits from rings, restoring peak compression, ensuring maximum Power and Efficiency.

These two factors - Injector spray pattern + Engine Compression - are Vital to Maintaining and Restoring Power & MPG.

A Google search for BG Products, or for example BG44k, BG's best-selling premium fuel system
cleaner, brings up many, many positive recommendations. Here are just three testimonials:

(Had his 2012 Mercedes CLS350 CDi circa 70,000 miles serviced with BG Engine Performance
Restoration flush and BG 245 Diesel Fuel System Cleaner) -- In truth, I first thought it hadn't
made much difference other than giving the car a little more poke than usual. However after a
few trips circa 120+ miles it was evident that the car was running much more economically. No
word of a lie the car is running 3 to 5 mpg better now if not more and proof is that it has
increased the overall mpg, which you will know takes some doing.

Last august I bought a Smart ForTwo expecting to get a good fuel economy, only having just over
nineteen thousand on the clock. Didn't happen – only about 41 to 43mpg on average and so agreed
to a BG Fuel Saving Service. Was I surprised afterwards. After a short trip of about 18miles I
returned to the garage and said "Where did you put the second turbo?" as the car had never
responded like that before. Well folks, see the improvement getting even better and not over
just a short period but over 1,381 miles so far and I will still be checking and reporting the
results so keep looking. Tank 1: after 260 miles 43.03mpg - Tank 2: after another 277 miles
48.40mpg – Tank 3 after another 219 miles 46.20mpg - Tank 4 :after another 129 miles 45.81mpg -
Tank 5: after another 276 miles 49.28mpg - Tank 6: after another 220 miles 52.13mpg - These are
the results so far and I would like to say well done and thank you BG products for turning my
car around. Loving the performance and didn’t expect these results. Awesome!!!!!

(Mercedes Diesel with carbon build-up affecting the DPF, restored by BG DPF & Emissions Service)
– This car has been well looked after and always had its services etc. But I’ve honestly never
enjoyed driving it so much. It’s now a pleasure to drive instead of a burden. The car’s like a
new one.

(Carbon) Deposits are a by-product of combustion. These deposits attach themselves to many parts of
the engine, including those critically important to the performance and economy of the engine -
Fuel Injectors, Piston Rings and various sensors. If fuel injectors are dirty this will interfere
with the efficiency and effectiveness of the fuel spray pattern. Deposits behind piston rings will
restrict the ability of the rings to seal and therefore can cause a loss of compression
(essentially the engine's power).

Decarbonisation or engine carbon cleaning usually refers to the process of removing carbon deposits.
BG Products develop and manufacture their own high quality chemistry and delivery systems to do
this, safely and effectively. Other proprietary systems use different classes of chemistry,
hydrogen, hot water or warm oil.

Deposits will form in only a few thousand miles. Annual preventative maintenance using BG Products will stop that decline and keep YOUR engine running efficiently and producing less particulate matter.

Deposits attach themselves to any part of the engine they come in contact with. This can include injectors, sensors and piston rings. BG removes deposits from these critical areas to restore missing power and performance.

Standard car servicing simply can't remove the power and MPG-sapping deposits that accumulate in your engine. BG's advanced fuel system cleaners and Oil Conditioners help to keep your engine clean and running more efficiently, for longer.

Former Stig Ben Collins is one of many advocates who have Tested and Recommend BG.

Chemical research company BG Products have been developing solutions to engine deposit and oil sludging issues for over 40 years. Industry guru Frank Massey uses and recommends a BG Products EPR flush and BG System Cleaner on every serviced vehicle - "The products work. The effects are real."

Declaring himself "normally sceptical", Motoring expert Quentin Willson has said he's impressed by BG's range of fuel system cleaners. In his Sunday Mirror Motoring column on 9/11/2014 Mr. Willson featured BG44K and BG244 as recommended products to improve MPG, engine responsiveness and reduce smoke.

Former Stig, Ben Collins tested BG with objective data provided by a rolling road dyno before and after the BG Powerflow treatment. The effects were significant. Horsepower was 22% higher on the test vehicle and post-service there was additional 43 ft/lbs of torque.

BG Products were founded in 1971. Their goal was, and still is, to produce the best products in their class. BG have worked with many of the world's OEM's to provide solutions to the deposit and lubrication challenge that modern engines create.

The Need for BG Quality: The Worldwide Fuel Charter, a document published by all the major engine manufacturers, states that 'deposits left by fuel will affect performance, increase emissions and reduce mpg'.

BG Quality: BG Products' quality is rooted in the challenge that modern engines provide. Modern engines are very susceptible to the deposits created by the demands of emissions control devices and tighter engineering tolerances demanded by higher output, lower emissions units.

The BG Difference: BG set out to make the best products in their class. For instance, many fuel system cleaners can clean injectors and some can even clean some soft baked carbon. BG fuel system cleaners contain more of the chemistry recommended by the engine manufacturers themselves to remove the hard baked carbon deposits that interfere with efficient flow of air and fuel, throughout the entire system.

Modern diesel vehicles by law include sophisticated emissions-control systems. These include a Diesel Particulate filter (DPF) which literally filters the amount of particulates passing into the atmosphere. It can reduce this amount by 80% - so does an extremely valuable job in lowering emissions... Until it gets clogged up by the very exhaust-borne emissions it's trying to control.

A level of particulate matter production is to be expected. Soot and ash, after all, are standard by-products of the combustion process. But what exacerbates the problem is poor combustion and oil evaporation which lead to excessive amounts of these deposits.

Annual preventative maintenance with BG Products' high quality chemistry will significantly reduce any deposit build-up, keep your engine running efficiently and produce less particulate matter, critically those components important to the performance and economy of the engine - Fuel Injectors, Piston Rings and various sensors. If fuel injectors are dirty, it will interfere with the efficiency and effectiveness of the fuel spray pattern. Deposits behind piston rings will restrict the ability of the rings to seal, causing a loss of compression and letting oil vapours blow-by and enter the exhaust stream. BG's twin-track fuel AND oil system cleaning regime combats all these issues.

Under normal conditions, the DPF is designed to use the very high temperatures created in the exhaust while the engine is under load to oxidise and evaporate the trapped particulate matter, thus cleaning (regenerating) itself. However, if this does not take place (perhaps because a high rev. journey did not happen for long enough) the particulate matter will continue to build up to a point that the DPF cannot regenerate itself - And this is also where BG's extensive R&D produced an effective solution.

The BG Diesel Intake and Emissions System Service uses innovative technology to restore the DPF, while simultaneously performing an intensive system clean. The service tool commands its own regeneration by controlling air intake flow and EGT (Exhaust Gas Temperature) to very precise levels. Once regen temperature is reached, BG's chemistry is used to clean soot right from intake all the way through to the DPF to be burned off and sent out the tailpipe.

Industry expert Frank Massey tested BG's Diesel Intake and Emissions System Service and achieved a 90% soot reduction. His Picoscope pre- and post-treatment readings can be seen on the right. This method means that BG don’t just clean the DPF filter but also treat the cause of the excessive soot too. Consequently the vehicle will have a cleaned DPF and also a better performing engine!
